Title: Device for measuring pressure
Inventor: UCHIYAMA TAIZO
IPC: G01L17/00
Filed: 1988-12-28
Abstract: PURPOSE:To reduce an error in pressure measurement due to non-uniformity of a tube by providing a tube pressing element which presses parts in the axial direction in front and the rear of a position of the tube pressed by a pressure detecting element, with a slightly smaller pressure than the pressure of the pressure detecting element. CONSTITUTION:When the internal pressure of a tube 8, i.e. an object of measurement, is zero, the tube 8 is set in a tube insertion part formed in a housing 6 of a pressure detecting unit 2. On the occasion, the tube 8 is positioned at the center of a pressure sensing element 4. Then, a cover body 7 is fixed in a closed. The sensing element 4 is subjected to a slight force when the cover body 7 is closed, and therefore the sensing element 4 generates a slight offset voltage. In the output of a pressure sensor, a positive voltage is generated from the offset voltage when a positive pressure is applied inside the tube 8, and a negative voltage is generated from the offset voltage when a negative pressure is applied. By subtracting the offset voltage from a voltage generated under some pressure P, in this constitution, an output voltage for this pressure is obtained. Based on this output voltage, a measured pressure is displayed in a measured pressure value display unit 3.

Title: Semiconductor device
Inventor: YAMANO TAKESHI
IPC: H01L21/762
Filed: 1990-11-28
Abstract: PURPOSE:To provide a MOS transistor with normal characteristics by forming an isolation gate electrode in an insulating film under a semiconductor layer, and using the isolation gate for an isolation MOS transistor that isolates ordinary MOS transistors when it is cut off. CONSTITUTION:An isolation MOS transistor is formed to surround an ordinary MOS transistor under a semiconductor layer 3. The isolation MOS transistor includes a gate 10, source/drain regions 5 and 4 of the ordinary MOS transistor, and a region outside the gate 10. When the isolation MOS transistor is cut off, the depletion layer spreads to the upper part of the channel region 6. As a result, the ordinary MOS transistor surrounded by the gate 10 of the isolation MOS transistor is separated from the outside. This eliminates the need for the removal of the semiconductor layer 3 to prevent the formation of a parasitic MOS transistor, so that a MOS transistor with normal characteristics can be obtained.

Title: Heat body detecting device
Inventor: MASUO YOSHIHISA
IPC: G01V8/12
Filed: 1987-12-28
Abstract: PURPOSE:To perform stable, high-accuracy detection by providing a comparing means which decides whether or not there is a heat body in a prescribed area and a means which gives hysteresis to a threshold level. CONSTITUTION:Background temperature varies corresponding to ambient temperature and when the ambient temperature approximates the temperature of the surface (cloth surface) of a human body, the S/N of the background and human body decreases and it becomes difficult to detect the stationary human body. Specially, when threshold level width VTH is fixed and large although the difference between, for example, background temperature and human body surface temperature is small, there is the possibility of misdetection. For the purpose, a circuit shown in a figure is used instead of a hysteresis circuit 14 provided to a comparing circuit 13 and the threshold level width VTH is decreased automatically when the difference between the background temperature and human body surface temperature is small and decreased when the difference is large. Consequently, even if a detection signal level varies, its influence is eliminated.

Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared detecting element having a higher sensitivity by a method wherein insulators having a thermal expansion coefficient equal substantially with that of infrared detecting bodies are arranged in such a way that the gaps between a plurality of the infrared detecting bodies on a substrate are filled with the insulators. SOLUTION: CdTe layers 20 are respectively deposited on the whole surfaces of elements in a necessary thickness (c), the surfaces of the layers 20 are polished and the surfaces are etched to remove crystal strains, which are generated in the layers 20 due to the polishing (d). After that, electrodes 16 are formed by a lift-off method (e) and (f). CdTes have a thermal expansion coefficient roughly equal with that of a HgCeTe crystal and are an insulator.
